METAL WHEEL FOR VEHICLES.

Specification of Letters latent.

Patented J an. 31, 1922.

Application filed March 31, 1920. Serial No. 370,312.

To all whom it may concern: Be it known that PAUL AiMii TREPIER, residing in Paris 11, Rue Dupont de lEure, France, have invented new and useful Improvements in or Relating to-Metal Wheels for Vehicles, of which the following is a specification.

This invention relates to those metal wheels for vehicles, in which the core of the smaller diameter than that of the first one,

this second disc being secured to the hub, so that the wheel can be made detachable by separating the two discs.

In the accompanying drawings,

-Figure 1 is a cross-section of a single wheel according to this invention,

Figure 2 is a front elevation of the same wheel, the left hand portion showing the wheel fitted up, whilst from the right hand portion the detachable disc is removed.

Figure ,3 is a cross-section of a two-rim wheel, and

' Figure 4 is a partial view, similar to that of Figures 1 and 3, of a modified construction of the disc.

The wheel (Figures 1 and 2') is constituted by a fixed central disc 2 and a detachable disc 1. The disc 2 is secured to the hub 3 and to the said disc are permanently secured the fixing bolts 6 and the plates 10 which are welded or riveted he disc 1 is secured to the rim and centered on the hub 3. It is provided with holes for the passage of the bolts 6 and each hole is strengthened by a washer 7 welded or riveted. The disc 2 is stiffened by a flange 5, on the circumstance of which is mounted the disc 1 and recesses are provided in the latter for the pamage of the washers 7 The fixing is done by means of nuts 8.

When assembling, the disc 1 is first mounted on the shoulder 9 of the hub 3, the tightening of the nuts then bend it so as to bring it into contact with the flange 5, and then, at each bolt, with the plates 10. The result is that the disc 1 is firmly pressed against the disc 2 and resists any lateral shocks well.

The twin rim wheel -(Fi re 3) is constituted by two detachable dlscs 1 and 1 arranged back to back and connected to one and the same central disc 2 secure d to the hub 3. The fixing is the same for both being done by means of bolts 6 and nuts 8.

The disc 1' is pressed against the shoulder.

9 and the flange 5 asin Figure 1. The disc 1 is in contact with the disc 1 at its central portion, and the three discs are firmly pressed against each other. Circular corrugations 11 stiffen the sheet metal between the bolts.

. I'nFigure 4, a flange 5 is provided upon the central disc against which is pressed th disc 1, the flange 5 being continued by a cylindrical portion 12 intended to form a, brake drum;

What I claim as my invention and desire to secure b Letters Patent is:

1. A veh cle wheel comprising two discs of unequal sizes connected together by bolts,

the larger one being secured to a rim, whilst the smaller one, secured to the hub, rests at its outer circumference against the larger one.

2. A detachable vehicle wheel comprising two discs of unequal size and bolts connected to them, the larger disc being secured to a rim, whilst the smaller disc, secured to the hub, rests at its outer circumference against the former, the wheel being detached by separating the two discs.

3. A detachable twin vehicle wheel comprising two discs, each secured to a rim, arranged back to back and connected by bolts to a third smaller disc secured to the hub, the three discs resting against each other around the circumference of the small disc, the wheel being detached by separating the three discs.

4. A detachable vehicle wheel, comprisingunequal discs connected together. by bolts, the large disc being secured to the rim, whilst the smaller one, secured to the oaeee hub, is arranged so as to form a brake drum, o. A vehicle Wheel comprising a plurality 1o the Wheel being detached by separating the of connected metal plates, said plates being discs. 7 1 dished oppositely to each other, one of said 5. A vehicle Wheel comprising a plurality plates having an integral seat for the hire 5 of connected metal plates, one of said plates rim and the other of said plates having an being dished inwardly and the other of the imeg'ral brake drum, and means for seeur- 15 said plates being dished outwardly, and a mg said plates together. brake drum integral with the last mentioned plate.
